	 * The Capabilities class provides properties that describe the system and
	 * runtime that are hosting the application. For example, a mobile phone's
	 * screen might be 100 square pixels, black and white, whereas a PC screen
	 * might be 1000 square pixels, color. By using the Capabilities class to
	 * determine what capabilities the client has, you can provide appropriate
	 * content to as many users as possible. When you know the device's
	 * capabilities, you can tell the server to send the appropriate SWF files or
	 * tell the SWF file to alter its presentation.
	 *
	 * However, some capabilities of Adobe AIR are not listed as properties in
	 * the Capabilities class. They are properties of other classes:
	 * 
	 *
	 * There is also a `WD` server string that specifies whether
	 * windowless mode is disabled. Windowless mode can be disabled in Flash
	 * Player due to incompatibility with the web browser or to a user setting in
	 * the mms.cfg file. There is no corresponding Capabilities property.
	 *
	 * All properties of the Capabilities class are read-only.
